I've learned the hard way, many times over, that for where I'm at right now, it's often not helpful to label my days, or my state of wellbeing, or anything else about my journey, more than is absolutely necessary. My internal saboteur is still very active and often comes along to undermine my good days with shaming cries of "yeah but still not good enough...", or to cruelly remind me the next day that I'd been doing so much better yesterday, so what happened today... etc.
I realise this is just my own personal fragility at the moment, but honestly, I try to just take each day, and each moment, as it comes, to focus non-evaluatively on the feelings and experiences I have at any given time, and to enjoy the better feelings and experiences while they're here, without forming too many conclusions about them or what they mean.
We all define good and bad differently, as well we would, because we all value different things in our lives and recoveries. Of course some days are better than others, and sometimes there are obvious reasons for this that I can identify, and sometimes my world just hums along a bit more smoothly for reasons known only to the internal workings of my brain.
It's nice, carefully, to sometimes take quiet note of observations such as "I seem to be a bit more functional thesedays than I was a couple of months ago..." etc, but as I said, I do try to avoid anything more specific than that.
